Aconcerted effort by the school administration and the parents is needed to encouragre and toassist in implementing these plans.

The school 15 located in an urban setting wtth a traditional street rid network Due to the smallblock size, it was not possible to locate parking facilities on the same lalock with the schoolbuilding. Three pull-out. loadin areas have been created on the block immediately adjacent tothe new school buiidnist to provide a limited amount of loading area outside the travel lanes andto avoid pedestrian street crossin On Crawford Street, an off-street pullout (separated by ai c u. i 1 i beet c1 icect L ‘ in io moc i ii rtth ti,1it cliOn 9th Street. a recessed curb loading area has been provided that can accommodateapproximately eleven passenger vehicles. The recessed curb loadin:z area on Patton Street isintended to serve school buses only and can accommodate the four buses that are expected toserve the site.

School Hours

The school is expected to operate on a uniform daily schedule. Classes on typical school days forall grades will hetin at 5:30 AM and conclude at 3:30 PM While these are the scheduled classtimes, it can be assumed that not all students will be picked-up and dropped-off at these exacttimes based upon normal distribution patterns. occasional special events at the school thatenerate traffic outside the traditional peak drop—off and pick—up periods may also occur: whilesome of the measures piesented in this report may be applicable in those instances ecial eventtraffic characteristics ate not covered in this analysis.

Bus Loading/Unloading

The existing Adamson High School is served by four school buses. This servzce is expected to heiuicharu’ed for the new school, The pullout located on Patton Street shall he dedicated to. all bu

Morning Drop-Off Period

Because the morning drop-oft is typically a quick operation and is more tern oraflv distrrhuted,vehicle queuing typically does not a significant amount o± space. Drop-oft procedures areexpected to occur and be adequately accommodated within the recessed. pullout areas along 9th

Street and Crawford Street and remain su cieritly out of the travel lanes, Off-streetloading. unloading of passenger vehicles is expected to only he necessary during the afternoonpick-up period, however in overflow or heavier than expected rnorrnng drop-off conditions, theprotocol for pick-up as described below imw also he utilized.

Afternoon Pick-Up Period

Afternoon pick-up is typically the condition that requires traffic manapement due to themagnitude of traffic converging at the site concurrenth, The following sections describeDeShazo’s recommended protocol.

While it may he acceptable to utilize the 9th Street and Crawford Street pullouts for passengerloading of przva te automobiles during afternoon pick-up periods.

Queue Lengths

DeShazo observed queuing behavior at the existing school during the afternoon pick-up periodto estrmate the future queuing demand. Vehicular queuing IS not expected to changeappreciably as enrollment zs expected to remain consistent, DeShazo observed a ma\Imum of ovehicles queued around Adamson Hih Shool along and Storev Streets at the time of studentrelease on ditferent days of observations.

The observed vehicles did not form a true queue line and load sequentrailv Rather, parentsparked along the curbsides of the streets adjacent to the huiding and passenger loadingoccur red in a very impromptu manner. Parked vehicles maintained sufficient space cm the streetto allow one through lanes open to traffic : NOTE: currently, the street operates as one-way, totwo travel lanes exist in each directioru. Motorists did not advance as closer vehicles loaded anddeparted curb spare ahead of tht’m,

The expected maximum queue of 5o vehicles can be accommodated in the iwo parking lots asseen in Exhibit 3. The path may be altered while remaining entirely within the parking lots toprovide additional queue length or to simplify ii given length is excessrve.

Pick-up Locations

For afternoon pick-un operations passenger loading should take place along the northeastcorner of the southwest parking lot mear the corner of Crawford and 9th Streets to result in the

A secondary loading area is available in the southeast lot — either inthe vicinity of the remote educanonal butldint. or in the northern portion of the lot nearStreet: however, passenrer loadin2 should not he allowed upon imrned:ate entry to the lot asthis will not allow much queu:ng space to avoid back_up onto Street. These locations allowstudents, as needed, to cross at crosswalks around O. and Crawford and would irovide amplevehicle queuing length on site assuming vehicles proceed to the south and loop around theparking area hefoe picking-up passengers.

Circulation

For the southwest parking lot, vehicles should enter from the Crawford Street driveway. Trafficcones or similar devices should be placed within the lot to facilitate the one-way circulationpattern depicted in Exhibit 3 to provide neessarv queue length. After passenger pick-upvehiLles may pioeed to the e>it at the Stoiev Street driveway.

For the southeast parking lot, tratfic should enter from the driveway on 91 Street, proceed southto central parking hays and circulate within this lot to orient with the passenger side near thedesignated pick-up point, Traffic cones or similar devices may he used to reinforce the propercirculation pattern. Vehicles would then continue nor th and exit via the same driveway on 9th

Street.

All internal circulatron wrthin this hit durmn peak hours is dericteLi in Exhibit 3 to provide thesafe arid efficient transportation for the students.

Personnel Assistance

it is rmportant to have starf presence wherever students are dropped-off orpmcked-u, :ncludingthe hu area. Because of the urban nature of the school and the proxin’utv of public streets. staffis especially needed to maintain order and safety among pedestr:ans and motorists, In themorning, there should he at least hvo staff menthers at the bus chop-off anti each of the recessedparent dropoff locations to guide vehicles to designated locations and direct students into thehool building.

Because it is a high school, students do not need as much assistance finding and loading mbtheir vehicle in the afternoon as compared to students in earlier rades. At this time, assistanceof school personnel is more needed to ovem see operations and ensure students and parents arefollowing ThIP gurdelines. A greater presence is needed in the afternoon due to the increasedtraffic and pedestrian activity

The school staff will need to be more involved in supervmsing students crossing the public streetsto the loadin locations mn the parkin lot Staff will also need to provrde emirorcement to ensurethat parents are unliZ:nr the designated queue and not loading students along the school’sperinmeter curb. ‘hOE: I”.’ -,;‘:‘:::d ::‘ ‘ :‘ :‘‘,: ‘.‘ ‘ls

Pedestrian Crossings

Passenger loading unloading in the parking lots requires students to cross Stieet and or(ran-turd Street in order to reach the designated off-street loading areas of the parking lots.Even though pedestrian crossings may occui at an intersection with or without markedcrosswalks, DeShazo does recommend that marked crosswalks along all four legs of the 9th

Street-Crawford Street intersection to increase awareness of motorists and pedestrians.Additional safety measures may also improve the pedestrian environment such as a school zonespeed reduction tthis implementation will be subject to the review by the C itv of Dallas PublicWorks and Transportation Departments.

NOTE A mid-block crosswalk on Crawford Street is also proposed to align with the securedwalkway between the new and existing high school buildings. This will accommodate studenttraffic during class changes during the school day. It is not an integral part of the TMP,

SUMMARY!CONCLUSIONS

The following roadway modifications were recommended by DeShazo in the Traffic impactAnalysis report for the Adamson High School and were assumed to occm, cr ci icrl7c in thisTMP.

1. Convert Crawford Street from 9th to 5’9 as well as 9- Street from Crawford to Patton)into permanent one-way streets operating northbound and westbound, respectivev.

2. Convert Storev Street and 9’ Street from Becklev to Crawfordi into permanent two-waystreets,

3. Install All-Way STOP Control at the intersection of 3th Street and Crawford Street.[NOTE: this is t’ie reconuneuclation of the Public Works and Transportation Departmentstaff.]

4. Install All-Way STOP Control at the intersectron of 9 Street and Crawford Street.

3. Install crocswalks around the inteiection of 91 Street and Crawford Street.
